HASVP-LOCK.

SPECIFICATION forming part of Letters Patent No. "771,814, dated October11, 1904.

Application led December 31, 1902. Serial No. 137,301. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH DAvY, acitizen of the `Republic ofv France,residing at Oakland, in the county of Alameda and State of California,have invented certain new and useful Improvements in Hasp-Locks, ofwhich the following is a specification.

My invention relates to locks, and more particularly to that classl ofsuch devices in which a hasp-fastener and a lock are combined in thesame structure.

In the patent granted to me January 9, 1900, No. 640,637, I provided thelock portion with two reciprocating spring-pressed pins or plungers, oneof which was adapted to be operated by the key and to in turn operatethe other plunger and withdraw the locking pin or bolt which formed apart thereof; but I have discovered that by the use of a different formof key I can dispense with one of the plungers and operate the otherplunger and lock with the key direct, thereby simplifying theconstruction and making a safer and more desirable lock.

The accompanying drawings illustrate the present invention and form apart hereof, the same reference character indicating the same part ineach of the views in which it occurs.

Figure 1 is a plan view of a lock embodying my invention,the hasp beingshown closed and locked in full lines and unlocked in dotted lines. Fig.2 is a similar View, the hasp being broken away and the top of the lockremoved. Fig. 3 is a view in longitudinal side elevation of theconstruction represented by Fig. 1. Fig. 4 is a sectional view showingthe position which the parts of the lock occupy when the key isinserted. Fig. 5 is a similar view showing the key after it has beenturned preparatory to withdrawing the bolt. Fig. 6 is a similar viewwith the key forced in and the bolt withdrawn. Figs. 7 and 8 arerespectively a side elevation and an end view of the bolt receptacle orcasing. Figs. 9 and 10 are similar views of the bolt. Fig. 11 is apartly-broken side view of the key.

Referring more particularly to the drawings, 1 indicates the shell orcase of the lock, which shell or case is secured to a plate 2 in anysuitable manner, preferably by means of long in cross-section andextends from the bottom of the shell I above its said cavity 4 to theplate 2 and is clamped therebetween when the plate is riveted to theshell. A thin flat projection or leg 8A extends from the lower end ofthe casing 7 and fits in the recess or cavity 4 to assist in holdingsaid casing from turning when the lock is being operated. The casing 7is further provided with a longitudinal bore 9, within which is placed alongitudinally-mov able bolt 10. The side of the casing 7 adjacent tothe guide-pin 5 is slotted longitudinally, as at 11, into the bore 9 andnotched along one edge to form stops or wards I2, the bottom of thenotches being preferably inclined, as shown at 13. The bolt comprises apinlike locking portion, (marked 10,) a cylindrical central portion 14,which iits the bore 9 of the casing 7 and from which the part 10projects, and a guide-strip 15. The pin 10 is of a less diameter thanthe central portion 14, and thereby forms a shoulder 16, which engageswith the plate 2 when the bolt is projected outward into its locking oroperative position. The guide-strip 15 extends from the shoulder 16along one side of the central portion 14 and projects below the endthereof and terminates in a step 17. lt iits within the slot 11 of thebolt-casing and prevents the bolt from rotating on its axis While beingoperated and holds the step 17 at the bottom in a line with the bits 18of the key 6 after they have passed the wards 1Q and the key is inposition to be forced inward to withdraw the bolt, the step being atsuch a distance of the end ward as to permit the entrance of the bit ofthe key.

A spring 19 is placed in the bore 9 below the bottom of the centralportion of the bolt IOO lcavity Ll.

'movement of the key can only occur when the key has been rotatedsufficiently to permit a iin or projection 2O on its stem to enter theslot or elongated portion of the keyhole 21, formed for the passage ofthe bits 18. The lin 20 is preferably formed diametrically oppositethese wards, so that the key must be given a half-turn before it can bepushed in to withdraw the bolt.

The plate 2 is adapted to be secured in position by means of screws inthe ordinary manner and has upon its exterior a substantially U-shapedstaple4 or staple-like projection 22, provided with annular ends 23. Oneleg of this staple is formed upon or secured to the plate 2 and theother one is directly above the first leg and at such a distancetherefrom as to admit of a locking-bar 24 being mounted so as to swingbetween them. The bar 24 pivots upon and around a hollow bolt 25, withinwhich is formed the keyhole 21, and which bolt passes also through theannular ends 23 of the staple. As shown, the hollow bolt has a flange 26at its outer end, which is seated on the ringof the upper leg of thestaple, and at its inner end it is rigidly secured to the plate 2. Thelower leg of the staple is provided with a perforation 27, which extendsthrough the plate 2 and through which perforation the pin portion 10 ofthe locking'- bolt projects to prevent the bar 24 being swung into itsreleasing' position, which is all that is necessary when the box orother receptacle to which the lock is applied is empty; but when it isdesired to more securely fasten the lock the end l() is caused to entereither one of two holes 2S, which are formed in an expanded portion 29of the bar, the same being adapted to be swung' between the legs of thestaple until either hole 28 registers with the hole 27 in the lowerleg'.

rl`he lower leg of the staple 22 is of substantially the same thicknessas the hasp, (herein marked 30,) which it is designed to receive, sothat when the hasp is turned down with its slot 31 fitting over theU-shaped staple the locking-bar 24 can be swung cross- Wise of the legsof the staple and will thereby prevent the removal of the hasp. The bar24 is pivotally mounted somewhat olf its center, and therefore has oneend longer than the other, which keeps it from passing' between the legsof the staple at the closed end. Itis understood that' the hasp 30 isflexibly secured at one end to one portion, as 32, of the receptacle towhich it is applied, while the lock is secured to another part, as 38.

In operating my improved lock when it is only desired to give it whatmay be called partial security the locking-bar is turned into alinementwith the legs of the staple on the lock, and the hasp is thrown downover the same. The bar is then turned laterally to one side or theother, which Will cause the end between the legs to be moved from overthe bolt and release the same, so that the spring can force it outward.It will now be impossible to return the bar to the required position forreleasing the haspuntil after the bolt has been forced in, and thus isobtained ordinary security; but when it is desired to more securelyfasten the bar against being returned to its opening position theperforated end is swung around until the bolt can enter one of theperforations, in which position it will be impossible to withdraw thebolt by any means except by inserting' the key into the.

keyhole. After the key has beeny inserted and has engaged the shoulderformedby the juncture of the shell 1 and thecavity 4p it is given apartial rotation untilitsfin willenter the bit-slot of the keyhole andthen it iS, forced inward, which causes one of. the bits of the key,preferably the end one, toengage with the step on the inner end of thebolt and force the bolt inward against the tension ofl its spring. Inthis position the bar can be turned to lock or unlock the hasp, afterwhich the key can be removed from the lock byreleasing' it and lettingthe spring forceit out until the lin is abovethecasing, when a partialrotation Will bring the bits into register with the bit-slot and permitthe removal of` the key. This lock, it will beobserved, is

capable of the same generaly application asy that of my previous patentaforementioned. Thus, for example, it is well adapted for use on boxesand chests of every description,

packing and shipping cases, gates, freight-car.

doors, &c.

I have shown and described hereink what I consider the simplest andcheapest form` of my improved lock; butitis evident that many changescan be made in the same Without departing from the fundamental principleof; my invention. For instance, the number., ar. rangement, and relativedirectionof thebits of the key and coacting partsofthe lock can,

be varied indelinitelyfand the lock may be made much more complicated,if deemed desirable. I therefore reserve the. right to make all suchalterations or modifications as come Within the scope of` my invention.
